What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
If you're going through hell, keep going.
You never know what motivates you.
Wherever you are - be all there.
Do not weep do not wax indignant. Understand.
I can, therefore I am.
Without hard work, nothing grows but weeds.
Never complain and never explain.
A wisely chosen illustration is almost essential to fasten the truth upon the ordinary mind, and no teacher can afford to neglect this part of his preparation.
